Abstract
To provide a resonator that includes a resonant tunneling diode that can generate an electromagnetic wave. In the resonator, the resonant tunneling diode and a resistor layer are sandwiched between first and second conductors in a direction approximately perpendicular to the in-plane direction of the resonant tunneling diode. Further, the in-plane cross-sectional area of the resistor layer is larger than that of the resonant tunneling diode. Further, the width of the in-plane cross-sectional area of the resistor layer is more than twice as large as the skin depth of an electromagnetic wave to be caused to resonate.
